Hi, Sandy, thanks for asking! I looked it up for you. I haven't been able to source such beautiful green pistachios in the recent years myself but the recipe is fairly simple.

180g best quality white chocolate (with good amount of cocoa butter in it)80ml double cream1 tsp vanilla paste or seeds from one vanilla pod100g pistachios, finely ground or even ground to a paste75g extra green pistachios, finely chopped, for the outer layer20 to 25 large whole pistachios, for the centre

Heat the cream and gently melt white chocolate in it, don't be tempted to stir too much. Add vanilla and the 100g finely ground pistachios. Mix and let chill in the fridge.When the mixture has cooled and hardened enough to handle, take two teaspoons of truffle mixture, place a whole pistachio between the halves and roll together into a ball. Next, roll it in the pistachio crumbs to cover evenly and place on a papertowel-lined tray. Continue until you run out of truffle mixture. Place truffles in the fridge to chill for a while, covered.
